Which is uni directional bus?

Address bus is also called a unidirectional bus.

Address bus is Unidirectional because the microprocessor is addressing a specific memory location. No outside devices can not write into Microprocessor. The Data bus is Bidirectional because the Microprocessor can read data from memory or write data to the memory. Normally Control bus is unidirectional.
